Patent EP-0426336-A2 (EP)
Inventor: ANDERTON DAVID O
IPC: H04M11/06
Filed: 1990-10-19
Abstract: A transmission arrangement is disclosed which facilitates compression of modem modulated facsimile signals for transmission on digital facilities. The presence of a facsimile call is detected and facsimile control messages are obtained by demodulating and interpreting the facsimile call control protocol (111). A controller (114) is responsive to the obtained control messages for controlling a voiceband encoder (110) to encode the control portion of the facsimile call and for controlling a so-called facsimile page demodulator (112) to demodulate any facsimile page portions of the facsimile call to obtain a baseband digital bit stream. The encoded control portion of the facsimile call and the baseband digital bit stream representative of the demodulated, i.e. compressed, facsimile page portion of the facsimile call are transmitted along with control information (as side information) to a receiver (103). At the receiver, a replica of the original modem modulated facsimile signal is reconstructed in response to the control information and by decoding the control portion of the facsimile call and by remodulating the digital bit stream representative of the facsimile page portion of the facsimile call.

Abstract: A catalyst composition includes a zirconia support on which is dispersed a limited amount of ceria to provide a zirconia/dispersed ceria support, and a rhodium catalytic component. The ceria content of the zirconia support does not exceed about fifteen percent by weight based on the combined weight of ceria plus zirconia. The resultant cat­alyst composition enhances the efficiency of three-way con­version catalyst systems in which it is employed, possibly by promoting the water gas shift reaction and the steam re­forming of hydrocarbon. The rhodium on zirconia/dispersed ceria support may be combined with a catalytically effective amount of a platinum catalytic component to provide an ef­fective three-way conversion catalyst.

Abstract: This invention relates to a method of determining the optimal recording power for an optical disk apparatus. Specifically, the apparatus, which records a signal on a recording medium through the projection of a laser beam at two levels of bias power and peak power, initially records a signal on an assessment track by decreasing the peak power progressively, with the bias power being fixed, determines the lower-limit peak power based on peak power immediately before the reproduced signal is first judged to be unsatisfactory by reproduced signal quality discrimination means (6), subsequently records a signal by decreasing the bias power progressively, with the peak power being fixed, determines the lower-limit bias power based on bias power immediately before the reproduced signal is first judged to be unsatisfactory by the reproduced signal quality discrimination means (6) adds prescribed powers to the lower-limit peak power and bias power thereby to evaluate the optimal peak power and optimal bias power for the optical disk apparatus, and performs the recording of user data with the optimal peak power and optimal bias power.

Abstract: In a ballast circuit for producing a DC signal with a high voltage amplitude, a capacitor is connected to a circuit output. The capacitor stores a charge which provides the high voltage amplitude of the DC signal. Current from an inductor is used to charge the capacitor. A current gate, when it is turned on, drains current from the inductor. A control circuit turns the current gate on and off so that the amplitude of the current drawn from the incoming AC voltage signal is in phase with the amplitude of the voltage of the incoming AC voltage signal. The control circuit includes a ramp generator which generates a pulse modulation reference signal with a varying voltage amplitude and a comparator which compares the pulse modulation reference signal with the incoming AC voltage signal after the incoming AC voltage signal has been rectified and the voltage divided by a voltage divider. The comparator produces a first modulated signal. The control circuit also includes a second comparator which compares the pulse modulation reference signal with a feedback signal to produce a second modulated signal. A logical AND is performed on the first modulated and the second modulated signal to produce a control signal.

Abstract: An electronic element is provided which includes a pair of electrodes (10) (referred to as facing electrodes) formed within the groove of an insulating film (3) on the substrate (7), the end portions of the electrodes (10) being separated and facing each other in the groove. When a voltage of a predetermined value or more is applied between the facing electrodes (10), there occurs a cold cathode emission which causes a flow of electrons from one of the electrodes (10) to the other. At that time, the facing electrodes are melted by heat generated by the applied voltage, thereby attaining a short circuit or insulation between the facing electrodes (10). In this way, the electronic element of the present invention can perform the protection of semiconductor devices and semiconductor circuits. Moreover, the electronic element of the present invention can perform the operation of selecting a desired load resistance to be applied to a specific circuit.

Abstract: Conventional fan drives in motor vehicles have the disadvantage that, at low engine speeds, they deliver too little air even though more air is frequently required for cooling the radiator and other heat exchangers. It is therefore proposed to arrange a second fan, a so-called counter-rotor coaxially downstream of the first fan. This second fan can be switched in as required, i.e. in particular at low engine speeds. It is thereby possible to deliver more air for cooling. The counter-rotor is switched in by means of a clutch, either via a gear mechanism or a belt drive, the counter-rotor rotating in the opposite direction to the first fan and at approximately the same speed. The main area of application is in the cooling of motor vehicle engines. <IMAGE>
